Liquid Acid Anhydrides

Liquid acid anhydrides feature a low viscosity and excellent impregnating ability. When combined with a large amount of fillers, they help reduce costs, which has led to their widespread adoption in a range of applications, including for lamination, filament winding (FW) molded products, and electric insulation and sealing materials (impregnation, casting) used in various transformers, coils, and capacitators.
RIKACID MH-700 is a liquid alicyclic acid anhydride, mainly consisting of 4- methyl HHPA. It is suitable for use in epoxy resin curing agents and gives a clear and colorless finish to products.
RIKACID MH-700G has improved features in heat resistance, color stability and degassing. This user-friendly product gives molded epoxy resin products a clear and colorless finish.
As an alicyclic acid anhydride developed by New Japan Chemical Co., Ltd., this epoxy resin curing agents is extremely suitable for optic electronic materials such as LEDs.

Solid Acid Anhydrides

RIKACID TH (THPA) and RIKACID HH (HHPA) are used as curing agents in transfer molding processes. THPA is used as a general-purpose item, whereas HHPA is used particularly in cases that require a colorless and transparent material.
These acid anhydrides form a low-viscosity liquid at curing temperatures and exhibit excellent impregnating ability, adhesiveness, and electric insulation, among other properties.
Our TMEG series of acid anhydrides are a collection of polyfunctional acid anhydrides that offer exceptional heat resistance when solid. They are used as curing agents in powder paints and coatings for exterior finishes on coils, hybrid integrated circuits (IC), and capacitors.
RIKACID TMEG-500 and 600 are used as curing agents for powder epoxy resins and improve adhesion and flexibility. TMEG-S is used in heat-resistant insulated varnish. TMEG-100 and 200 are used as raw materials in polymides and polyamide-imides.
RIKACID TBN-100 is an acid anhydride that allows for curing epoxy
